LAM P-EXTINGUlSHING APPARATUS.

SPECIFICATION forming part of Letters Eatent N 0. 412,969, dated October15, 1889.

Application filed January 15, 1889. Serial No. 296,381. (No model.)

To all whom it may concern.-

Be it known .that I, JOSEPH MILLER, of Olean, in the county ofCattaraugus and State of New York, have invented a new and usefulLamp-Extinguishing Apparatus, of which the following is a full, clear,and exact de scription.

My invention relates to an improvement for automatically extinguishinglamps, and has for its object to provide a simple and reliable devicecapable of attachment to any lamp, and wherein, should the lamp beoverturned or thrown a great distance out of perpendicular, the flamewill be immediately and automatically extinguished.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a central vertical section through a lamp having myimprovement attached, and Fig. 2 is a similar section through a lamp,illustrating a modified view of the invention.

In the form of device illustrated in Fig. 1 the lamp-body is providedwith a vertical tube 11, extending from the bottom at the center upwardwithin a distance of the burner. The body 10 of the lamp, containing thetube 11, is supported, preferably, upon a tubular pillar 12, attached toor integral with the hollow base 13, and the said base 13 is in turnsupported upon a sub-base 1 1, having an opening in the upper surface,the wall of which opening is struck upward to form essentially a flange15.

The wick-tube 16 of the lamp-burner 17, which may be made of anyordinary construction, is provided with a vertically-adjustable sleeve18, to which sleeve at one side the upper extremity of a rod 19 isattached. The rod 19 is made to pass down through the bodytube 11 adistance below the same, and in the tubular pillow 12 a second rod 20 ispivotally attached to the lower extremity of the upper rod 19, and thelower extremity of the lower rod 20 is pivotally secured to a dishshapeddisk 21, which. disk is adapted to close the upper opening in thesub-base 1 1, the periphery of the disk 21 being flanged downward tooverlap the flange 15 of the sub-base.

To the under side of the disk 21 a pendulum-weight 22 is secured bymeans of apendulum-rod 23. Thus should the lamp by any possibility bethrown any great distance out of perpendicular the pendulum-weight 22will be carried to one side, as illustrated in dotted lines, and thedisk 21 will be thrown upward at an angle to the sub-base, whereupon therods and 19 will also be carried upward, which rods will force thesleeve 18 above the upper end of the wick-tube and the flame willbeinstantly extinguished.

It will be observed that by reason of employing two rods 19 and 20 andpivotally connecting the same a positive operation of the device isassured, since the greatest throw of the pendulum-weight 22 will notcause the joint to more than contact with the sides of the tubularpillar 12.

In Fig. 2 the tube 11 in the body 10 of the lamp is dispensed with, andthe lamp-body may be mounted upon any suitable or desired pedestal. Theburner 17 is, however, provided with a longer body than is usuallyemployed,and the collar 24 of the burner, adapted to be secured upon thelamp-body, is carried inward, the flange upward, as illustrated at 25.The disk 21 is made to rest upon the inner surface of the said collar,and the pendulum-weight 22 is rigidly secured to the bottom of the saiddisk in substantially a similar manner to that illustrated in Fig.1.Above the pendulum-disk 21 a second essentially cup-shaped disk 26 isplaced in the body of the burner, adapted to be normally sustained bythe lower disk, and the upper disk 26 is connected by a rod 27 with thesleeve 18 of the wick-tube.

In the operation of this form of device, should the lamp be tilted toany great extent, the pendulum-weight will swing to one side, asillustrated in dotted lines, whereupon the lower disk 21 will beelevated, which in turn, by contacting with the upper disk 26, willelevate the same, and by reason of the rodconnection between the upperdisk and the sleeve 18 the said sleeve will be carried in aperpendicular line above the upper extremity of the Wick-true, and thesupply of air being thus cut off the flame is at once extinguished. Thewick passing fromthe wick-tube 16 may be carried through the tube-disks21 and 26 to the body of the lamp in any suitable and approved manner.

I desire it to be distinctly understood that while specific constructionhas been shown and described equivalent construction may be employedWithout departing from the spirit of the invention.

The light Will not be extinguished when the lamp is slightly tipped-asin carrying it, for instance-as the sleeve will not be carried up farenough to affect the flame until the lamp is carried far enough out ofperpendicular to bring the edge of the disk beyond the center of theweight below-that is, the weight must be swung far enough to throw itbeyond a perpendicular line extending down from the edge of the diskwhen in its normal position.

Having thus described my invention, whatI claim as new, and.desire tosecure by Letters Patent, is-

1. The combination of a lamp having inwardly-extending annular shoulderor flange, a loose disk resting upon said shoulder or flange, and apendulum-weight secured rigidly to the center of the disk, with amovable eX- tinguisher on the burner-tube and a rod depending therefromand operated by the tilting of the disk, substantially as set forth.

2. The combination, with a lamp provided with a vertical tube attachedto the bottom of the body, a disk loosely supported in the lamp belowthe said tube, and a sleeve adj ustably held upon the wick-tube abovethe body-tube, of a pendulum-weight attached to the under side of thedisk and a jointed rod connecting the disk and the wick-tube and passingupward from the body-tube of the lamp, all combined for operation as andfor the purpose specified.

JOSEPH MILLER.
